Check engine light on? Best guess.....dirty fuel filter, or fuel pump leaking pressure off, causing it to need to prime every start. Check the fuel pressure when starting it to verify it is fuel.

Have you checked the fuel pump its self? Usually when you turn the key to the ACC position it sends power to the pump before the engine cranks. If its going bad it may not be pressurizing the fuel system, hence the motor is starved for fuel until pressure come up in the system. Normally you can hear the fuel pump run for a few seconds before cranking. I cant say for sure thats your problem, but I would start by checking that first.

turn on the key for about 10 seconds before trying to start it
